BOX-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 518,002, dated April 10, 1894. Application filed November 22,1892. Serial No. 452.847. (N model.)

To all whom it may concern.-

Be it known that I, WILLIAM S. Dore, of,

and useful Improvement in Box-Nailing Machines, of which the following is a specification.

This-invention relates to machines for driving nails in boxes and it consists in a rotary and vertically movable table and the means for automatically causing these movements; and it further consists in the construction and novel arrangement of parts as hereinafter setforth.

I have not deemed it necessary to show or descrlbe means for supplying nails to the pockets or to particularly show and describe the drlving mechanism, as such features are fully shown in certain patents, notably my Patent N 0. 461,013, of October 13, 189i.

In the accompanying drawings, Figure 1 is a front elevation of a box nailing machine cmbodylng my improvement. Fig. 2, is a vertical section thereof. Fig. 3, is an elevation of a portion of the machine at right angles to Fig. 1. Fig. 4, is a transverse section on the line I, 4, of Fig. 1, looking upward. Fig:5 is

a detail portion of the machine shown in elevation. Figs. 6,7 and 8, are detail sectional views of the vertical movable ring. Fig. 9, is a detail sectional view of table. Fig. 10 is a detail sectional view of hand-wheel; and Fig. 11,1s a top view of the standard andflange showing the means-of adjustment.

Referring by letter to the drawings, A, is a supporting standard extending upward from a base A. This standard is hollow or tubular and consists of two parts a, a, one part being horizontally adjustable relatively to the other, as will be more fully described hereinafter.

B, designates the driving shaft having a band wheel B, thereon and havinga hearing at one end in a post B and at the other end in the standard A. The portion a, of the standard A, has secured to its upper end a flange, a and the portion a, has an annular flange a adapted to rest on the flange a Bolts a extend through slot openings in the flange a and engage in tapped holes in the flange (1 By this construction the part a, which carries the nail punches and pockets,

I nail pockets 0. I

may be moved backward or forward to adjust the nail pushers and pockets in these directions, to regulate for diflerent thickness of stuff being nailed. r

O, designates a cross-head'secured to a ring 0', which is reciprocated vertically on the part a, by means of the rod 0, which is pivotally connected at its upper end to a bar 0', extending from the ring 0, through vertical slots 0 in the part a, of the standard. The lower end of the rod 0, has a crank connection 0 with the shaft B.

0 shows arms adj ustably connected to and extending outward from the cross-head C. At the rear end each arm 0 has a T shaped rib b, engaging in a longitudinal T shaped groove 1), in the upper side of the cross-head, so that these arms may be adjusted longitudinally of the cross-head to accommodate them to different sized boxes. They may be secured as adjusted by means of thumb screws. The arms 0 have the nail drivers, or pushers, O

adjustably attached to them in .the usual manner.

0 shows arms for supporting .the usual These arms at their rear ends have a T shaped rib b to engage a correspondingly shaped groove in a fixed bar C, so that said arms may be adjusted to the proper position relatively to the arms 0 A back stop 0, is secured to the standard A, below the bar 0 This stop serves to prevent the boxes being nailed from being pushed too far back. 4

D, designates a table for supporting boxes during the process of nailing. The table may be adj usted vertically by hand-power to bring it to its lowest required position relatively to the nailing mechanism, and it maybe adj usted vertically to another position by automatic means. This last adjustment is caused by a rotary movement automatically imparted to the table. The table D, has a central tubularhub-like portion (1, surrounding the standard A, and normally resting on the top of a ring D. This ring D, has lugs (1', projecting fromits innerside through vertical slots 0?, in the standard A, so that said ring may have a vertical movement on the standard, but not a rotary movement.

D shows a nut, the interior thread of which engages the threaded portion (1 of the standard A, and this nut has attached to it a handwheel D The ring D, rests normally on the top of the nut D Clips E, have their lower portions movably seated in vertical grooves e, in the ring D, and coiled springs e are secured at one end to the clips and at the other end to the ring D. The upper ends of the clips E, have inwardly turned portions e which engage over an annular rib 6 on the hub-like portion (1. The lips E, and springs, serve to hold the table in yielding contact with the ring D, and nut D so that the table may be automatically moved Vertically while the ring and nut are at rest. Clips E, secured to the nut D have a hook portion engaging in an annular groove (2 in the ring D. Obviously by rotating the nut D the table D, may be raised or lowered on the standard A.

I will now describe the means for automatically raising and lowering the table.

F, designates a short vertical shaft having bearings in armsf, extending outward from the ring D; and F, is a gear wheel on the upper end of said shaft meshing with gear F on the hub-like portion d, of the table D. A ratchet wheel F is secured to the shaft F, below the upper arm f, and a pawl carrying arm f, is supported by, but has a rotary movement on the shaft F. This arm f, has at one end a ring which loosely surrounds the shaft F, but it is prevented from moving longitudinally on the shaft by means of a collar f affixed to the shaft. A pawl f is pivotally connected to the arm f, and engages with the ratchet F F is a curved lever pivoted between its ends to a part projecting from one of the two opposite arms G, extending from the ring D. At its inner end the lever F is slotted as shown and a pin g, extends from the end of the arm f, loosely through said slot. A rod G has a pivotal connection with the outer end of the lever F and at the other end is connected to the crank 0 The arms G, extend outward and upward from the ring D, and have rollers g, at their ends. At opposite sides the table, on its under surface, is provided with ribs G 5 these ribs G, are arranged in the arc of a circle and are adapted to engage on the rollers g", as the table D, revolves.

In operation the table is adjusted first by means of the hand-wheel D to accommodate it to the height of end pieces of a box with one side piece thereon. At this stage, the ribs G, must be on the rollers g, so that the box will be raised to the proper level. The nailing mechanism is now operated to force nails through the side piece into the end pieces, vice versa. On the downward movement of the cross-head C, the pawl will be rotated around the ratchet wheel without imparting movement thereto; but on the upward movement of the cross-head the pawl will be moved in the opposite direction and engaging with the ratchet wheel, will rotate the table D, one-fourth revolution, and bring the rollers g, to bear on the under side of the table between the ends of the ribs G, thus lowering the table and allow the opposite side or end of a box, placed on the table between the ends of the ribs, to be nailed on.

Of course boxes to any number may be placed on the table and as the table revolves, they will be brought to the proper position beneath the nailing mechanism.

Having described my invention, what I claim is- 1. In a box nailing machine, the combination with a standard, and a non-rotary driver or punch of a table, surrounding the standard and adapted to support a numberof boxes to be operated on successively and having a rotary and vertical movement relative to said standard, and means for causing said movements, substantially as specified.

2. I11 a box nailing machine, the combination with a standard, comprising two portions, the upper portion being laterally adjustable upon the other and carrying the punches and pockets, an annular table surrounding said standard and adapted to support a series of boxes to be nailed successively, means for adjusting the table vertically and means for rotating it, substantially as specified.

3. In a box nailing machine, the combination with a standard, having an exterior screw thread of a table having a vertical and rotary movement thereon, a nut for causing a vertical movement of said table, a yielding connection between said nut and table and mechanism comprising a pawl and ratchet mechanism operated from a driving shaft for causing a rotary and vertical movement of the table, while the nut is at rest substantially as specified.

4. In a box nailing machine, the combination with a standard having a threaded portion thereon, of a rotary and vertically movable table, a threaded ring, a ring movable vertically on the standard, arms extending therefrom, rollers in the ends of said arms, arc-shaped ribs on the under surface of the table adapted to move on the rollers as the table is rotated and means operated from a driving shaft for rotating the table, substantially as specified.
